JWT Authentication in Laravel: Complete Guide

Laravel is the most popular PHP framework. Laravel Passport and Laravel Sanctum provide JWT-like token authentication, while tymon/jwt-auth offers full JWT support. This guide walks you through everything you need to implement robust JWT authentication in Laravel, from choosing the right library to writing production-ready code.

JWT Authentication Code Example

Below is a practical code example showing how to implement JWT authentication in Laravel using tymon/jwt-auth. This snippet demonstrates the core pattern you will use in most applications:

Laravel — JWT Exampletymon/jwt-auth
use Tymon\JWTAuth\Facades\JWTAuth;

class AuthController extends Controller
{
    public function login(Request $request)
    {
        $credentials = $request->only('email', 'password');
        
        if (!$token = JWTAuth::attempt($credentials)) {
            return response()->json(['error' => 'invalid_credentials'], 401);
        }
        
        return response()->json([
            'access_token' => $token,
            'token_type' => 'bearer',
            'expires_in' => JWTAuth::factory()->getTTL() * 60,
        ]);
    }

    public function me()
    {
        return response()->json(JWTAuth::parseToken()->authenticate());
    }
}

This example shows the essential JWT workflow in Laravel. In production, make sure to store secrets in environment variables, use HTTPS, and implement proper error handling for token expiration and revocation.

How to Set Up JWT in Laravel

Follow these steps to get JWT authentication working in your Laravel project. Each step builds on the previous one, so we recommend following them in order:

  1. 1

    Install: composer require tymon/jwt-auth

  2. 2

    Publish config: php artisan vendor:publish --provider=TymonJWTAuth

  3. 3

    Generate secret: php artisan jwt:secret

  4. 4

    Configure auth guard to use jwt driver

  5. 5

    Create AuthController with login/me/logout methods

Key Features of JWT Auth in Laravel

When you implement JWT authentication in Laravel, you gain access to several powerful capabilities that make your application more secure and scalable:

JWT auth guard
Token refresh and blacklist
Middleware groups
Eloquent user provider

Why Use JWT Authentication in Laravel?

Laravel is widely used for building modern web applications and APIs, and JWT has become the de facto standard for stateless authentication. By combining Laravel with JWT, you get a scalable authentication system that does not require server-side session storage.

JWT tokens are self-contained, meaning they carry all the information needed to identify a user and their permissions. This makes them ideal for microservice architectures, mobile backends, and single-page applications built with Laravel. Each request includes the token, so your server can verify identity without a database lookup.

The tymon/jwt-auth library makes it straightforward to implement JWT in Laravel. You can generate tokens on login, verify them on each request, and handle token refresh to keep users authenticated without interruption. Combined with proper security practices — such as short expiration times, refresh token rotation, and secure storage — JWT provides a robust foundation for any authentication system.

Best Practices for JWT in Laravel

When implementing JWT authentication in Laravel, follow these best practices to keep your application secure:

  • Use strong secrets: Always use a long, random secret key for signing tokens. Store it in environment variables, never in source code.
  • Set short expiration times: Access tokens should expire quickly (15–30 minutes). Use refresh tokens for longer sessions.
  • Validate on every request: Always verify the token signature and check expiration before granting access to protected resources.
  • Use HTTPS: JWT tokens sent over plain HTTP can be intercepted. Always use HTTPS in production to protect tokens in transit.
  • Handle token refresh: Implement a refresh token flow so users are not logged out when their access token expires. Rotate refresh tokens to prevent replay attacks.
  • Do not store sensitive data in tokens: JWT payloads are Base64-encoded, not encrypted. Avoid putting passwords or other sensitive information in claims.
